Removing Fender Frontman 15r Back panel

Use a Phillips #0 screwdriver to remove the four 21.7mm screws holding the back panel to the frame.

Once the screws are out, use a plastic opening tool or spudger to pry the top of the back panel open. There may be some resistance, but it will eventually pry loose.

Once the top is separated, use your hand to remove the back panel from the unit.
